IDW Comics just fails to commit.
Metal Virus Arc? Had zero negative impacts on anyone after the event despite being sold off as the most hopeless and traumatic arc in the comics.
Surge and Kit? They become heroes when their initial appeal was that they were villain versions of Sonic and Tails.
Mimic/Duo? Supposed to be a intimidating and unpredictable assassin. Only to be a dumbass that brought nothing but pointless drama that goes nowhere. Gets outed in the dumbest way possible and then, suicide bombs himself fighting Whisper.
Clutch? Similar thing, except he's now Eggman's puppet. Suppose to be a powerful mobster, only to be a pathetic jobber.
It brings in interesting ideas only to squander them with the endings.
